Abstract
Electrical storm (ES) is characterized by at least three separate episodes of ventricular arrhythmia (VA) over 24 h that require treatment or an incessant VA lasting >12 h. The incidence is higher in patients with implantable cardioverter-defibrillators (ICDs) in secondary prevention and the main manifestation is monomorphic VA. ES onset represents a major event in the history of patients with cardiomyopathies that significantly worsens prognosis. The management of ES is complex and requires a multidisciplinary approach including a comprehensive clinical assessment, resuscitation and sedation management skills, ICD reprogramming, ablation, and neuromodulation procedures. ES early recognition and prompt treatment initiation increase the chances of therapeutic success. Each one of these aspects will be properly discussed in the present decalogue. Notably, ES management remains a challenge, with only limited available evidence from small retrospective series and a substantial lack/limited number of randomized or prospective trials. The spectrum of available antiarrhythmic drugs is limited, as well as their efficacy. The future hope is that larger prospective studies will be able to answer important questions, concerning the most effective pharmacologic strategies, the timing for the invasive treatment, the indications for acute neuromodulation strategies and for the circulatory support tools.
